AAA320 Servo Accelerometer

Extremely rugged, ultra-low range servo accelerometer with taut-band suspension

About the AAA320 Servo Accelerometer

The AAA320 Series are high precision, closed loop, servo balance, ultra-low range accelerometers with high-level voltage output or 4 … 20 mA output that can be used for a wide variety of industrial applications. Despite its low measuring range the AAA320 Series are very robust and shock resistant. Electrical terminations are via 6-pin, bayonet lock connector or solder pins.

 

Key features AAA320

  • Fully self-contained – simply connect to a DC power source and a readout or control device for a complete operating system
  • High-level output signal
  • ±1/10 g to ± 2g ranges available
  • Extremely rugged, withstands 1500g shock

 

Applications AAA320

  • Geophysical, seismic and civil engineering studies
  • Flight test monitoring
  • Structural monitoring
  • Low acceleration analysis
